Question

The angles in a triangle are in the ratio 2 : 3:7.

Work out the size of the angles in the triangle.

Answer 1

30°, 45° and 105°

Explanation:

2 + 3 + 7 = 12 parts

180/12 = 15 degrees each part

First angle (2 parts)

2(15) = 30°

Second angle (3 parts)

3(15) = 45°

Third angle (7 parts)

7(15) = 105°

Hope this helps
